NCR paper and Its Cleaning

Carbonless copy paper is used for a million and one things in the world of commerce – whether it’s to make multiple copies of something or even to make a few copies here and there. It’s extremely useful when you need something that can be reused repeatedly and will be able to give you back its value time after time as an easy-to-use, convenient package.

An NCR form is made of one or more sheets of paper that are coated with miniature capsules containing either dye or ink and reagent clay, which cause certain areas to change their color when exposed to heat, pressure, static electricity, or various liquids.

An impact printer used in a time-clock system is what creates the tiny marks on the backside of the top sheet. What makes this mark permanent is the combination between a form and a high level of an oily substance called wax. After that, dye or ink is indirectly applied to fill in the print.

Scanning NCR paper

When using carbonless NCR type paper in our Truper scanners, heavy build-up of residual inks as well as other substances may occur. These substances should be cleaned off the paper more often than the recommended cleaning intervals according to the manuals and should do so after prolonged usage.

Every time you scan something with your scanner, it’s vital that you clean out the rollers to keep them in perfect working order. If there is dirt or any foreign material on the roller when you try to scan again, the scanner may get clogged and won’t be able to read any codes being scanned.

Scanner Cleaning

NCR™ type paper consists of fibers that tend to cling together. When scanning NCR, the computer in the scanner’s hardware detects any dirt on the sensor and thinks that this is an edge or the start of the 2nd piece of paper moving across its path. Böwe Bell + Howell recommend cleaning the scanner after every thousand scans or once per week, whichever comes first. It is good to clean it more if you scan more than one document per day.

Be sure to vigorously clean the rollers to get rid of any residue left by the NCR™ type paper, but never use a solvent or agent that might deteriorate the plastic or rubber head.

Do not use metal scrapers, tools, or scouring pads with the device because they may damage the rollers and/or scanner beyond repair. If you do so, there will be no available warranty on the device.

Cleaning roller

When cleaning your printer’s rollers, be sure to take particular care that the nozzle check contacts are made of nickel by using a magnet or screwdriver (Nickel is easily identifiable as it will attract to a magnet). Avoid getting liquid onto the nozzles or roller well shafts. Cleaners or spray solutions applied prior to passing through the suction will become encapsulated in the internal cavity and eventually dry out. This can lead to product failure while in use.


Use a 1.5-inch-by 4-inch piece of NCR Residue Cleaning Pad (S007611). Scrub residue off any free rollers by pressing gently into the roller’s surface and then pulling it across. Alternate scrubbing directions up and down until the residue has been lifted off the roller’s surface completely. Once each roller has been cleaned, vacuum around the machine thoroughly. Wipe the rollers in all the equipment with a lint-free cloth (S005660), and/or cleaning wipes (S007613).

Cleaning drive roller

Take one of the lint-free cloths (S005660) and a ¼” flathead screwdriver (not supplied). Using the lint-free cloth, cover the sharp tip on your flathead screwdriver. With your flathead pointed against a roller, run across the surface, parallel to the surface of the roller. Apply force with only the amount you need to until most of the material peels off. If some part of it doesn’t peel off right away, try again and apply more force as needed. After cleaning the residue off the rollers, make sure to use Tire Roller Cleaner (S003410) on a clean cloth and wipe each roller thoroughly. By wiping the scanner in all directions, first, use warm water to remove any loose dust and dirt.

Cleaning Adf section

Lift, rotate, and remove the Hopper Tray. Notice the notch in the side of the tray that glides smoothly over the Guide Rails. Closely follow all instructions outlined in your product manual to locate where your hands should be during this step to prevent accidental burns from hot steam or water. Pull the Exit Door Release handle towards you to release the Exit Door. Lift and pivot open the exit door in whichever direction will make it easiest for you to see into or place items into your machine’s cavity for cleaning.

Cleaning the inside of your scanner once you’re finished using it will not only prevent any further damage to the rollers from any chemical reactions but will also help maintain the good condition of the scanning device.
